2.创建用户、目录

useradd postgres
echo postgres | passwd --stdin postgres
mkdir -p /u07
mkdir -p /u07/pgsql
mkdir -p /u07/pg_data
chown -R postgres:postgres /u07
chmod -R 755 /u07

3.编译安装

./configure --prefix=/u07/pgsql \
--enable-cassert \
--enable-debug \
--enable-depend CFLAGS=-O0

make world&& make install-world

编译选项

--prefix= PREFIX 安装路径
--with-blocksize=BLOCKSIZE 数据库blocksize ,缺省8KB
--with-segsize=SEGSIZE 表文件的段尺寸，缺省1GB
-with-llvm 使用基于JIT的lIvm编译
存储过程语言支持
--with-tcl
--with-tclconfig = DIR
--with-perl

4.修改环境变量

vi  ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

export PGDATA=/u07/pg_data
export PGHOME=/u07/pgsql
export PGDATABASE=postgres
export PGPORT=5432
export LD_LIBRARY_PATH=$PGHOME/lib
export PATH=$PGHOME/bin:$PATH

source .bash_profile

5.初始数据库

initdb -D $PGDATA -E utf8 --wal-segsize=8
pg_ctl start
